Valorization of Greywater

Following up on the earlier post of Greywater in Africa, this posting discusses an interesting project that is underway in Tunisia. The Canadian-based International Development Research Center (IDRC-CANADA) is funding a greywater reuse and urban agriculture project titled "Collection of Greywater and Rainwater to Help Poor Communities in Ariana Soukra, Tunisia" that focuses on "... a participatory approach and aims primarily to improve the socio-economic conditions of Ariana-Soukra’s economically disadvantaged population by using rainwater and greywater for urban and peri-urban agriculture". According to this press release, The project is funded by the  for the period 2007-2011 and within the framework of the “Urban Poverty and Environment (UPE) program, which targets 8 other cities including North Africa, Asia, Latin America and the Caribbean.

The second stage of the project is described in this press release "...aims at creating farming production units through valorization of rain water to irrigate garden plants, and grey water (particularly from households, basins, bathtubs and washing-up) for watering decoration plants and trees". Not being an economist, I had to look up "valorization" which is defined by The Free Dictionary as "To establish and maintain the price of (a commodity) by governmental action". I can then only assume from the brief articles that greywater and rainwater are being "valued" as part of this project, and that the "value" will be sanctioned by the government.

Recalling my temporary duty in Italy where I was training 10 engineers and hydrologists from a broad spectrum of African nations, along with my research on transboundary aquifers, I am learning very quickly that the Africans are taking a no-nonsense approach to water resources, literally squeezing "more crop per drop". Perhaps the perceived water problems in the US could learn something from examining how water is managed in Africa, and that includes dealing with the often-unmentioned aspects of corruption in the water sector.
